Basic knowledge of high precision stamping parts and features of stamping parts
The general situation and inner function of the sheet material used for high compact stamping parts have a great influence on the quality of the stamping products.General bright, no spots, no scars, no abrasions, no general cracks, etc.The bending strength is average and there is no basic knowledge and characteristics of the stamping parts.Average elongation rate is high;The ratio of bending strength is low;Processing softening is low.
In the real production, often use and stamping process similar to the process of technology experiments, such as deep drawing function experiment, bulging function experiment and other inspection materials of punching machine energy, to ensure the quality of products and high pass rate.
The precision and layout of die directly affect the forming and precision of stamping parts.Die production cost and life is the main factor that affects the cost and quality of stamping parts.When the mold assumption and the manufacture demand are more, this delays the new stamping production preparation time.Shenyang nut flush rod mold base, the scale of the die set, guide and grow a brief simple mold (for small batch production), compound die, multi-station progressive die (for mass production, and developed rapidly in mold assembly, stamping can reduce yield amount things preparation and contract preparation, can make us to cut stamping production amount things preparation and contract preparation, can make its progress and is used to measure more elder stamping craft fair right for small batch produce variety.
Stamping equipment in addition to thick plate with hydraulic forming machine, the general use of machine press.With modern high-speed multi-station machine press as the middle, set up equipment and equipment such as uncoiling, leveling, product collection, transportation machine and mould library, and quick die change assembly, and operate computer French control, can form the active stamping production line with high yield.
In every minute production of dozens, hundreds of stamping parts of the environment, in a long time to complete the feeding, sea nut punching bar stamping, parts, waste discharge and other processes, often produce personal, equipment and quality changes.Therefore, the stamping in the quiet production is a very major problem.
High compact stamping is the first metal or non-metal sheet, with the help of the pressure of the press, guangzhou nut punch through the stamping die stamping process, it has the following characteristics:
(1) high compact stamping parts is in the material consumption is not big condition, after punching out of the suppression, the parts weight is light, good stiffness, and the plate after plastic deformation, the metal internal structure layout has been improved, so that the strength of stamping parts has improved.
(2) high-compact stamping parts have higher dimensional accuracy, average difference with module dimensions, and better interchangeability.General assembly and utilization requirements can be met without further machine processing.
(3) high compact stamping parts in the process of stamping, because the general situation of the material is not crushed, it has a better general quality, the surface is smooth and beautiful, which is the general situation of spray paint, electroplating, phosphating and other general situation disposal supply a convenient premise.Basic knowledge of high precision stamping parts and principles of stamping parts characteristics
(1) the envisaged high compact stamping parts must meet the product utilization and technical functions, and can be easily assembled and repaired.
(2) the high compact stamping parts should be beneficial to improve the handling rate of metal materials, reduce the types and specifications of materials, and reduce the material consumption as far as possible.Adopt expensive materials in the permitted environment, try to make the parts have no waste and little waste blanking.
Closely stamping parts required (3) the idea of high appearance is simple, reasonable layout, based on the number of beneficial to simplify the mold layout, simplify the process, which is at the very least, the most simple stamping process complete parts processing, cut processing, in other way again and is pressing manipulation, convenient for construction realization and active machine produce, produce with progressive labor rates.
(4) the assumption of high compact stamping parts, in the general use of guarantee energy environment, as far as possible to make the size of precision grade and the general situation of the coarse grade requirements lower, and conducive to the exchange of products, cut the finished product, guarantee the quantity of products unchanged.
(5) the envisaged high compact stamping parts, should be beneficial to the use of existing equipment, process equipment and process flow to stop its processing, and conducive to the extension of the service life of the die.
